Is there a Debian/ArchLinux supported webserver which is of a "transitional package" (fully-rolling release, without leaps like from Apache 2.4 to 3.4 to 4.4 and so forth)?

Something that even Ansible could fully continuously-upgrade?

I ask this due to this question and comments by @StephenKitt

Q: How to enable and disable Apache modules with Ansible in a version-agnostic way?

After I install Apache2 with Ansible, I should execute a2enmod http2 deflate expires. a2enmod or a2dismod are non version-agnostic commands. The Ansible Apache docs doesn't include a non version-agnostic syntax of these commands (unlike Ansible's apt module's state: latest option for example, t...

hi

i need help in the find command

can someone help me

i've need one help in linux find command. lets say i've 10 files which is created today. i want to use the find command to keep the latest two files and delete the rest of the files. But using only find command `find . -maxdepth 1 -type f -name 'file*'` and NOT using pipe out to `sort -rn | tail -n +2 | xargs -rm`
?

@JohnDoea What do you mean by “fully-rolling release” for a web server?

@Stuxnet78 Questions similar to this have been asked multiple times on the main U&L site. You should be able to find them by searching.

@Stuxnet78 You will have more people looking at your question posting in the main site and not here. If you already done it in the main site, please do not post here also.

@ClausAndersen One reason I dislike emojis is that apart from the most common ones, I can almost never tell what the are supposed to be. I don't have good eyes. Is that a monkey? Aah, a reference to that monkey discussion... I never fully understood it.

@Kusalananda It was just triggered by the little Dr Seuss poem I wrote:

@JeffSchaller Tsk, wasted opportunity there: My day is complete, my monkey fed, I answered a question, I answered with ed!

Kusalananda

12:32 PM

@terdon If a thousand monkeys were given an ed editing session, would they still be able to exit it?

Stephen Kitt

@Kusalananda what kind of keyboard and keymap are they using?

(I’ll suggest ignoring the probability that they manage to enter a key-remapping command)

Kusalananda

@StephenKitt Do they care? I think it's more a matter of what the size of the keys are.

Stephen Kitt

@Kusalananda the probabilities depend on the number of directly-accessible characters ;-)

Kusalananda

True, that.

Stephen Kitt

Is there a nice diagram of the ed state machine somewhere? Asking for a friend

Kusalananda

12:37 PM

Hmm... interesting question. I don't know.

Also, my search history now includes "keyboards for monkeys".

Stephen Kitt

@Kusalananda yes, that just popped up on FiveEyes

oops

Kusalananda

@PrabhjotSingh I just signed a do-not-resuscitate form for my mother. From what I can tell, it doesn't look like she is going to live much longer. Thanks for your help with this.

@llllIIIIIllllllIIIIIIlllII You are probably not here but just in case... Please see Jeff's Question-and-Answer about writing a well-received question. Asking "I wrote this shell script, what do you think about it?" is not the type of questions that we deal with really. Instead, a question should focus on ideally one thing that you are having an issue with.

goodguy5

morning gents. I have a question that I know is here somehow, but I can't think of the right words to ask it (or find the existing one)

if I write a command and I want to output it to a file

Such as

foo.exe parameters > myfile.txt

But I don't want to write if there's an error.

What do I command?

Kiwy

error are usually send to stderr not stdout

to redirect stdout to file do
`command param > file` and stderr should be display in terminal

2:24 PM

@Kiwy yes, but that's not what I mean.

the file still gets blank written

Stephen Kitt

@goodguy5 please write it up as a question on the main site

goodguy5

oh, but putting it in graves didn't write a file, interesting

@StephenKitt Like I said, I'm also not sure the good words and I don't like putting up bad questions

I'm most of the way there, though

Stephen Kitt

@goodguy5 other users will help you find the right words (or the duplicate question if there already is one)

in chat you’ll only get the ideas of the users present in the chat, there are far more active users on the main site

goodguy5

2:39 PM

@StephenKitt I think that I've gotten my thoughts to where I want them. blank output

Kusalananda

3:04 PM

@goodguy5 The shell would create the file that you redirect to even before the command executes, so there is no real way you could catch an error and not create the file. You may however catch an error and remove the file with utility >file || rm -f file.

goodguy5

@Kusalananda oh, interesting. I didn't realize that. Though, I guess that makes sense once I think about how the Shell actually does things.

@RuiFRibeiro @JeffSchaller it's hard to reach, but your monkey goal sound a lot of fun I shall help you in any way :D

Rui F Ribeiro

@Kiwy His monkeys! ;)

Jeff Schaller

@Kiwy if you have a hard-to-reach monkey, maybe it's because he's on your back?

Kiwy

@JeffSchaller Ho my god a monkey on my back ? I didn't notice though, but those sneaky b******ds are good

Rui F Ribeiro

@JeffSchaller I used to monkey around with my daughter, when she was younger saying she was opening a school of monkeys because she was always picking her nose.

My fav TV serie used to be "12 Monkeys"

Jeff Schaller

so much monkey business going on lately! illegally importing hypothetical monkeys, then feeding them, then giving them keyboards and an ed session

and now our chat star box is full of monkeys!

Rui F Ribeiro

Hey, stop monkeing around!

Jeff Schaller

My day is complete, our chat box is full of monkeys; we appear to be a bunch of U&L junkies

Rui F Ribeiro

Nah, a bunch of U&L monkeys ;)

Monkey overflow here in our chat box.....help me!

You need a monkey tag.....but I hope nobody posts questions about whether their monkey is pregnant.

I dont even got a cat and I know that by that time the litter is hidden somewhere. ;-P

4:49 PM

@StephenKitt by a "fully rolling release webserver" I mean to any webserver which is of non-transitional package, that is, a version-agnostic package apt update && apt upgrade, as well as Ansible's state=latest could both upgrade automatically in a single action without any manual intervention as should be needed in Apache (sadly, it really makes me sad).

Jeff Schaller

5:47 PM

@Kusalananda I don't know if it's possible, actually, but I'm wondering if you would take a 2nd look at unix.stackexchange.com/a/489511/117549?

IMHO it's a self-answer situation, although as I commented, it could use some help from the OP to make it clearer that it's an Answer.

Kusalananda

6:07 PM

@JeffSchaller I will look again shortly. Thanks.

@JeffSchaller I had a second look. The syntax is different from the code at the GitHub link that you posted. I really can't tell whether he's posting his attempted solution (a clarification to the question) or whether this is the real solution. I don't use NixOS, so I can't test it.

I've left a comment to this effect.

... roughly.

goodguy5

@JohnDoea Wait, what? I used to be a release manager, but I didn't follow what you siad.

Jeff Schaller

6:28 PM

@Kusalananda fair enough; thank you! There was another page on the NixOS github that showed the OP's Answer as a stock example of that parameter, so now I'm less sure, myself. Hopefully they can fill us in.

@Kusalananda also, in re: unix.stackexchange.com/posts/489532/revisions, the only quibble I have is that the OP (and my answer) specify -type f so directories shouldn't be matched. It's a good general clarification, though.

Kusalananda

@JeffSchaller If we're spending more time than him trying to understand the answer, then it's not an answer :-)

Jeff Schaller

@Kusalananda heh! I just happened to notice it when the Q was posted, and the A was posted at the same time, leading me down the "self-answered" path.

Kusalananda

@JeffSchaller Ah, sorry. I read the question as more general, but then again, I sometimes try to generalise my own answers a bit... Revert if it's not in your style.

Jeff Schaller

it's good info; I'm just not sure if it's distracting from the main point or not. I'm OK with it.

Kusalananda

@JeffSchaller Was this comment directed to reviewers or to the OP. I'm guessing the OP, right?

Jeff Schaller

6:49 PM

@Kusalananda correct; I quickly read the linked Q and wasn't sure if it emphasized that well enough

7:40 PM

ah, I see.

is making a local sym-link on each box an option?

I don't know anything about Ansible, but we used apache and not all of our boxes ran the same version

however, for stability and testing, boxes running the same product should be using the same apache version whenever possible
